UAS regulates expression of apn tagged with Tag:HA.
abnormal size | embryonic stage, with Scer\GAL4btl.PS
embryonic/larval tracheal dorsal trunk | embryonic stage, with Scer\GAL4btl.PS
extracellular matrix | embryonic stage, with Scer\GAL4btl.PS
Expressing apnUAS.Tag:HA under the control of Scer\GAL4btl.PS leads to a curly and over-elongated dorsal trunk tube and a reduction of luminal extracellular matrix components in stage 16 embryos. Cell polarity is unaffected.
